It) all whom "it may concern."

lie it known that l, TERRY L. HUAruLE, a t-itizen ot' the linited States, residing at 'loinpltiusrille in the county of It tonroe, Htate ot lieutuelty. have invented certain new and uselul Ilnproven'ients in Hail Joints; and i do hereh deelare the following to he a lull. t-lear. and exaet description ol the invention. sueh as will enable others sl illed in'the art to whieh it appertains to llttllit and use the same.

'lhis lHHlllltHt relates to a rail joint and has lltll2ll ret'et'enr-e. to a rail joint of the interloeltiug type.

()ne ()lljit't ot' the invention is to provide a rail joint ot this eharaeter having an improved torn] ol tongue and groove eouneelion nherehy tensiotroli the joint will tend to draw the sides of the groove together.

.\nother ohjeet of the inveutitni is to pro- \'ide a rail joint oi this eharaeter with a tongue and groove eonneetion provided with a stop flange so arranged that the rail head will l'orin a eoutinuons suriaee without the neeessit ot' holtintr the parts to gether.

With the ahore and other ohjt-t'ts in view, the intention eousists in general of a, rail having" a tongue extendingtherelroin, said tongue being ot' itnprored t'orni; in combination with a seeond rail having a reeess in the end adapted to elosel engage and lit said tongue.

The lIIYtHliHlt' further eonsists in eertain nmel details ol eonstruetion and eoiul ination of parts, hereinatter fully deseriheth illustrated in the aeeotnpatrring drawings and speeilienllj' set t'orth in the claims.

in the aeeonipanying; di-"awing s, like altar-- aeters o't' relerenee indieat'e like parts in the sereral views; and igure 1 is a top plan View of one form of the rail joint, Tdig. 2 is a plan View of a modified form. Fig. 3 is a side eleration ot' the tongue of the joint: shown in Fig. '1. Fig. 4 is a partial median se tiou ot' the end oi the mating; rail shown in i ig;

The numeral it) indieates one oi the rails and the ninneial it the mating rail then for. l'pon the end of the rail is formed a tongue 12 which extends vertieally of thel rail and which is provided with an enlarged end 13. In the preferred form as illustrated in Fig. 2 this enlarged end has undercut shoulder portions 14. in the form shown in 'l ig. 1 the enlarged end is simply in the form of a hull) '14-. In both of these forms the bottom of the tongue and bulb are surrounded by an outwardly extending flange 15. i v

The mating rail is provided at the end with a Yertieallj' extending recess'ltl, ha'v inn un enlarged inner portion 11', to lit the enlarged end of the tongue and the muse oi this recess is peripherally rahbeted as at 18, to lit the. flange on said tongue.

In assembling the device it is merely necessary to drop the reeessed end of the rail all over the tongue on the rail 12, when the stop shoulder formed on the bottom of the tongue eauses the parts to so position themselves that the rail head forms a substantially unhrolten surt'aee.

llt is i'nrtherinore to he observed that in the preferred forms of this devil-"e the undereut shoulders of the tongue end eause the sides of the slot or reeess in the. mating rail to draw together and teusional. stress is plat-ed upon the two rails so thatthey tend to separate ltmgitndinallj'.

There has thus been provided a simple and etiieient device of the hind deseri'oed and for the purpose speeit'ed. I

it is obvious that ininor changes may he made in the form and pro-portions of this invention without departing 'flOlll the material principles lhereol. it is not: therefore desired to confine the invention to the exact, form herein shown and t leseril'ied but it wished to include all such as come within the scope of the appended claims.

Having thus described the invention, is claimed as new, is:---

1. in a rail joint, :1 rail hmring a rertieally arranged tongue projecting from the end thereof, an enlarged entl formed on said tongue, and a stop ll ngge extending laterally entirely around d bottom thereof; in (zonal 0nd rail having an end reel. gage the tongue, the tongue end,

flange.
